OpenGL.GL.GREMEDY.frame_terminator

OpenGL extension GREMEDY.frame_terminator

This module customises the behaviour of the OpenGL.raw.GL.GREMEDY.frame_terminator to provide a more Python-friendly API

Overview (from the spec)

This extension defines a mechanism that enables marking the end of render frames within the OpenGL stream.

When debugging or profiling an OpenGL application, the debuggers and profilers needs to know when a render frame is ended. This is important for frame per second measurements, statistical analysis, marking and clearing stream loggers logs, performance counters sampling and more.

When an application uses off screen buffers, the debugger / profiler cannot be guaranteed that the application will call a certain function at the end of each off-screen frame (e.g: SwapBuffers / glClear / etc). This extension enables the application to notify the debugger / profiler whenever a render frame is ended.

This extension is mainly useful for debuggers and profilers. It is not expected that standard drivers would implement this extension. The main point of having this extension is to allow applications to have a clean way of accessing this functionality only when they are run under the control of a debugger / profiler, without having to recompile or change the application source code.

The official definition of this extension is available here: http://www.opengl.org/registry/specs/GREMEDY/frame_terminator.txt
